How to check if an object is an array of a certain type

Question

I have an object Field field.

I'd like to check if field is either an object of type Foo or an array: Foo[].

Psuedo code:

if field.getType() is Foo || field.getType is Foo[]

Is this possible?

I've tried

if (field.getType().isArray())
    // do something

But this would only allow me to check if field is an array.

Doing this, on the contrary, will only check if it's an object of Foo

if (Foo.class.isAssignableFrom(field.getType())
     // do something

Any idea how to do this?

Thanks.

Simple compare should work

import java.lang.reflect.Field;

public class Main {

String[] myStringArray;
String[] myStringArray2;

Object[] myObjectArray;

String str;


public static void main(String... args) {
        Field[] flds = Main.class.getDeclaredFields();
        for (Field f : flds) {
            Class<?> c = f.getType();

            if (c == String[].class) {
                System.out.println("field" + f.getName() + " is String[]");
            } 
            if (c == String.class) {
                System.out.println("field" + f.getName() + " is String");
            }
            if (c == Object[].class) {
                System.out.println("field" + f.getName() + " is Object[]");
            } 
        }
}

}
